Glock makes some of the most popular handguns in the world, and that popularity can be ascribed to more than just aggressive marketing. The Glock is a very reliable, accurate and functional handgun, and for that reason is widely used by private citizens, military and police around the world.

However, due to that popularity, the one size fits all trigger configuration that ships from the factory may not be what you are looking for. An enormous aftermarket has arisen, and searching for the best Glock trigger upgrade may be like looking for a needle in the proverbial haystack. There are countless options, from simple upgrades to an otherwise stock trigger system to complete trigger replacements (and all are purchasable from Brownells).

We’ll take a look at a variety of Glock triggers, and let you decide which one is best for you.

Why Upgrade Your Glock Trigger?

A better question might be why not? While there are compelling reasons to avoid modifying the trigger on a gun used for daily carry, or at least keeping those modifications within a reasonable range, there are many compelling reasons to modify the trigger on a Glock used for sport shooting. In fact, it’s almost a requirement.

Glocks are sold to law enforcement and private armed citizens, and as such they are built with neither too heavy (Well, except for those goofy New York PD triggers) nor too light a trigger. There are tactical and even liability reasons for this, and any modification to a stock trigger on a carry gun needs to be carefully considered. However, while the factory trigger is a marvelous (and probably lawyer approved) combat trigger, it leaves a lot to be desired in the target shooting realm.

Glock pistols are extremely popular in competition shooting, including practical three gun competition and other shooting sports that attempt to replicate as much as possible real world shooting situations. Just like one would heavily tune a car used for racing, so too must they tune a gun used for sport shooting. One of the first places a sporting gun is tuned is in the trigger and for many very good reasons. The trigger is the heart of the whole process … certainly a high quality barrel is required, but a lousy trigger will make a match barrel a waste of money.

Even something as simple as swapping parts–trigger springs, trigger bar or trigger shoe–can lead to radical change and improvement over a stock trigger. The choice of which parts to swap out is entirely up to you. Some folks prefer a lighter but otherwise stock trigger, while others may wish to change the trigger shoe out to change how the mechanics of the trigger itself operates.

Whatever your reasons and choices though, there is a plethora of options, and the best Glock trigger upgrade is something of a personal matter and depends entirely on your budget, end use, and what you desire to turn your gun into. Fortunately, trigger upgrades and replacements are fairly affordable and when done right are a great way to turn your just like a zillion others Glock into a custom pistol that has been reshaped to fit your needs and desires. Upgrading your Glock trigger is easy and only needs to take a few minutes at the kitchen table, so the only question you should ask yourself is why you haven’t done so yet already?
